'llhis. invention; relates.- to dyeing machines of the circulatiomkind;.and;i particularly to machines of the type in which the dye iscaused to circulate in a direction which can be reversed at will by theoperation of a suitable valve. This invention has for its object animproved machine of this type in which the quantity of dye flowing inthe upward direction 'an be moderatel at will with a View to preventingthe fibers under treatment. from becoming entangled.

According to this invention I provide two chambers adapted to receivethe goods to be treated, said chambers being connected to the circuit ofa circulating pump through a re versing valve adapted to enable thedirection of flow to be reversed atwill in both chambers, and beingprovided with a single by-pass allowing the rate of upward flow of thedye in the chambers to be moderated at will.

Referring to the drawings filed which illustrate as an example aparticular arrangement of a dyeing machine made according to thisinvention Fig. 1 shows diagrammatically a plan of the circulatingarrangement;

Fig. 2 shows diagrammatically an elevation of the same;

Fig. 3 shows the internal arrangement of the two chambers, with racksadapted to hold the skein supporting-rods;

In Figs. 1 and 2, a and a are the two chambers, bis thepump causing thecirculation of the dye in the system, c is a four-way valve by means ofwhich the circulating dye can be sent to and pumped from a, and arespectively, or its direction of flow reversed. h is a by-pass by wayof whicha quantity of liquid, regulated by the cock is, can pass cit-herinto the chamber a, by the branch pipe m or in the chamber a by thebranch pipe 722,, according to the position of the fourway valve 0, asexplained hereafter. In the position shown, the liquid is sent by thepump Z2 into the piping 7 through the valve 0 and the connection 6 intothe lower part of the chamber (1 in which it rises and passes into thechamber (1,, by the two branches m m of the bypass, proceeds in adownwarddirection into the chamber a and thence, by the connection e,,the valve 0 and the piping 9, it returns to the pump 1). Now, with anormal rate of flow of the liquid upwardly in the chamber the skeinswould depart from their vertically hang ng position owing; to, theupward thrust of the flowing liquid, and would become entangled. Thecock la is therefore opened and. adjusted so that a certain proportionof the liquid delivered by the pump can pass in the bypass it, theamount passing through the pip.- ing 7, being just sufiicient to liftthe silk slightlyand so prevent any possibility of stick-marking,without in any way disturbing the condition of the hanks. In the chamber0-,, where the liquid is flowing downwardly, the rate of flow may beincreased without inconvenience, and this is obtained by the liquidflowing along the by- To pass 11 passing into the chamber a, by means ofthe branch 722,. In other words, there are two liquor circuits in theapparatus, namely bf0-a m m at 0gb, and b is hm, a, 0gb, these twocircuits being coincident along m,

a, c g I), so that on this latter portion of the circuit, aproportionately larger rate of flow of the dye is obtained, according tothe amount of opening of the cock is. On operating the valve 0, thedirection of flow is reversed the two circuits being now in coincidencealong the portion m, a 0 g b of the circuit, with a large downward rateof flow through the chamber a While there is a reduced rate of flowupwards in the charm-. ber 0 In Fig. 3, a, and at, are the two chambersas before, separated by a passage correspond ing to h, and communicatingbymeans of an aperture m with passages m, and m come sponding to thebranches of the by-pass of Figs. 1 and 2. Racks nare provided on thewalls of the chambers to receive the supporting rods p for the skeins q.The'two chambers communicate with the passage it by openas ings e 6,controlled by a reversing valve (not shown).

The chambers a a, and the passage ii. are closedby a panel provided withpackings ensuring a tight joint, under the pressure of a suitable toggleor other device, in the known manner. I

It will be understood that, although the arrangement described comprisesonly one pair of chambers, any convenient number of 1 such pairs ofchambers can be connected to the circulating system, a single by-passbeing used for the whole system. The invention has been described inrespect of dyeing but is clearly applicable to any case in which it isrequired to iruzdi iihers or other materials with n ciruuiu'liug liquid,for other purposes hesidos dyeing.
